Instant 1.0, a backend for AI-coded apps | Hacker News

Instant 1.0 is a backend that supports unlimited projects.

Traditional backends usually run on VMs, and starting many VMs is expensive.

Instant includes multiplayer, offline mode, and optimistic updates.

It also adds file storage, cursor sharing, and token streaming across machines.

A demo shows backend creation without sign-up and a real-time todo app in about 25 lines.
